Was poking around distrowatch (looking for what I might want to put on my XPS 13) and came across this Untangle "OS". Looked interesting so I went to their website. This thing is a full on firewall/web filter/whatever else! Has a free version to boot! Though honestly, for 50 bucks a year to get the full NG firewall setup (home users) I might get it and try it! Good way to really lock down your home network. Its only me on my network but this would be something that would be fun to play with and setup, and gives the added bonus of security!
